Jose Castillo

Diamondbacks Trade Jose Castillo To Mets

By Anthony Franco | May 15, 2025 at 9:35pm CDT

The Mets acquired lefty reliever José Castillo from the Diamondbacks for cash, the teams announced. New York designated righty Kevin Herget for assignment to create a spot on the 40-man roster. Arizona had designated Castillo for assignment on Monday.

Castillo has technically appeared in five MLB seasons, though all but eight of his appearances came with the Padres during his 2018 rookie season. He turned in a 3.29 ERA over 38 1/3 innings that year but was subsequently set back by injury.

The 29-year-old signed a minor league deal with the Snakes in November. It marked his second consecutive season in the Arizona organization. He had spent all of last year with their Triple-A team in Reno, though he lost the first half of that season to injury. The Diamondbacks assigned him back to Reno to begin this season. He struck out seven while tossing 5 1/3 innings of one-run ball and was called up at the beginning of May.

The 6’6″ southpaw only spent a couple weeks in Torey Lovullo’s bullpen. He didn’t pitch well, allowing eight runs on 10 hits (including a trio of home runs) over 6 1/3 frames. Arizona bumped him out of the bullpen when Kendall Graveman returned from injury. Castillo is out of options, so they needed to designate him for assignment to take him off the MLB roster.

That out-of-options status means the Mets are prepared to give Castillo at least some time in their big league bullpen. They’ve been forced to scour the lefty relief market after losing Danny Young and A.J. Minter to season-ending injuries. They called up Génesis Cabrera from Triple-A Syracuse. He’s the only southpaw in Carlos Mendoza’s relief corps. Cabrera has managed five innings of one-run ball over four outings, but he had walked nearly 15% of opposing hitters in Triple-A before the promotion.

The Mets will need to remove someone from the major league bullpen once Castillo reports to the team. Dedniel Núñez is the obvious candidate, since he still has a couple options remaining. Cabrera is out of options, so the Mets would need to designate him for assignment if they wanted to use Castillo as their only left-hander.

Herget relinquishes his spot on the 40-man roster. The Mets claimed the 34-year-old off waivers from Milwaukee early last offseason. He only spent one day on the MLB roster, allowing two runs on three hits in one inning. He has otherwise been working out of the bullpen at Syracuse. Herget has only allowed five runs over 15 2/3 innings, but that came with a pedestrian 13:7 strikeout-to-walk ratio. He had a much stronger 32.4% strikeout rate over 38 appearances with Milwaukee’s top farm team a year ago.

The Mets will likely place Herget on waivers within the next few days. He has been outrighted twice in his career and would have the right to elect free agency if he goes unclaimed.

Diamondbacks Designate Garrett Hampson, José Castillo For Assignment

By Steve Adams | May 12, 2025 at 3:27pm CDT

The Diamondbacks announced that they have recalled infielder Jordan Lawlar, a move that was previously reported. They also reinstated right-hander Kendall Graveman from the injured list. To open roster spots for those two, lefty José Castillo and infielder Garrett Hampson were both designated for assignment. The club’s 40-man roster count drops to 38.

Hampson, 30, inked a minor league deal in free agency and broke camp with the D-backs after hitting .283/.393/.348 in 56 trips to the plate this spring. He hasn’t been able to carry that production over to the regular season. He’s appeared in only 18 games and taken just 41 turns at the plate, batting .167/.359/.167 in that span. He’s been a pest for opposing pitchers in the sense that he’s taken 10 walks, but Hampson is also 5-for-30 (all singles) and has bottom-of-the-scale contact metrics when he’s put the ball in play.

Arizona is Hampson’s fourth team in four seasons. He spent the first five seasons of his career with the Rockies but since his final season there has had one-year stints with the Marlins, Royals and now D-backs. He hasn’t hit much in any of those spots, combining for a .237/.308/.323 slash in 750 plate appearances dating back to 2022. However, Hamspon is a plus runner (84th percentile sprint speed, per Statcast) who can be deployed virtually anywhere on the diamond. Even though he’s been seldom used with the D-backs, he’s still seen time at five positions: second base, shortstop, third base, left field and center field.

Castillo, 29, has spent the better part of the past half decade in injury rehab. Since a strong MLB debut with the 2018 Padres, the southpaw has been on the injured list due to a torn ligament in his pitching hand, a torn lat and Tommy John surgery. Just making it back to the majors in the wake of so many rapid-fire injuries is a feat, but Castillo’s brief time with the Snakes didn’t go well. He pitched 6 1/3 innings out of Torey Lovullo’s bullpen — already his most in a big league season since ’18 — and was pounded for eight runs on 10 hits and three walks with three strikeouts.

As a rookie, Castillo fired 38 1/3 innings of 3.29 ERA ball for the Friars, fanning a gaudy 34.7% of his opponents against an 8.1% walk rate. He was terrific in a small 5 1/3-inning sample in Triple-A Reno this year, allowing only a run on four hits and no walks with seven strikeouts and a 58% grounder rate. That performance could lead to some interest from other teams, although Castillo’s once-95-mph heater has understandably dipped to an average of 93.3 mph in the wake of all those injuries.

Both Castillo and Hampson can spend a maximum of one week in DFA limbo. The D-backs can look to trade them during that time or simply place them on outright waivers. Since waivers take 48 hours to process, the team has up to five days to orchestrate trades of either player, should there be a market. In the event that they’re placed on waivers and go unclaimed, both players have enough major league service time to reject an outright assignment in favor of free agency.

Diamondbacks Place Justin Martinez On 15-Day IL, Transfer A.J. Puk To 60-Day IL

By Steve Adams | May 1, 2025 at 11:23am CDT

The D-backs announced Thursday that they’ve placed closer Justin Martinez on the 15-day injured list due to right shoulder inflammation. Lefty Jose Castillo’s contract was selected from Triple-A Reno to take his spot on the active roster. Fellow southpaw A.J. Puk moves from the 15-day IL to the 60-day IL to create 40-man roster space for Castillo.

Martinez was set for an MRI this morning after experiencing an alarming velocity drop over the past week. He’s gone from averaging triple digits on his power sinker to sitting just 93.5 mph in his most recent appearance. Though the right-hander claimed he felt 100% healthy, he’ll head to the injured list with a still-vague injury designation. The D-backs will surely provide more information on his status and potential timeline later today.

This slate of injury-related moves is a brutal blow for a D-backs team that spent much of the offseason looking for established bullpen arms but wound up making generally smaller-scale moves. Martinez and Puk are the team’s two best relievers and entered the year as the favorites to work in save and high-leverage hold situations. They’re both on the shelf, and while Puk’s flexor strain won’t require surgery, today’s move to the 60-day IL only further underlines the fact that Arizona is going to be without him for quite some time.

Martinez, 23, averaged 100.2 mph on his sinker in 2024 and averaged better than 100 mph on the pitch in each of his first eight appearances this year. A dip into the 97-99 mph range over his next three outings was concerning but not necessarily cause for full-fledged alarm. Last night’s drop all the way to 93.5 mph, in an outing where he faced three hitters and allowed two walks and a home run, is another story entirely.

It’s become an ominous situation for D-backs fans to monitor, and one that’s compounded by Puk’s absence. Martinez broke out with a 2.48 ERA, 29.5% strikeout rate, 11.7% walk rate, 58.9% ground-ball rate, eight saves and seven holds across 72 2/3 innings for the Snakes last year. He clearly has some command issues, but the elite velocity coupled with plus strikeout and ground-ball rates helped to mitigate that bloated walk rate.

The D-backs, clearly bullish on Martinez’s future, signed him to a five-year, $18MM extension during spring training. The contract contains a pair of club options for the 2030-31 seasons, which would’ve been Martinez’s first two free agent years. At the time, there was little reason to fear an injury (beyond the general attrition rate of pitchers in today’s game). Now, the outlook is far hazier.

Were Puk healthy, the Diamondbacks would surely have just plugged him into the closer’s role and moved forward with Kevin Ginkel setting up. But Puk hit the injured list with elbow inflammation after a strong eight-inning start to his 2025 season, and a subsequent MRI revealed a flexor strain that’ll require a notable shutdown period.

With Martinez and Puk both shelved, the D-backs will likely turn closing duties over to a combination of Ginkel and Shelby Miller, who returned to Arizona on a minor league deal this offseason and has been outstanding after earning a job this spring. Ginkel only just returned from his own bout of shoulder inflammation, which sidelined him for the first month of the season. From 2022-24, he pitched a combined 164 2/3 innings with a 2.95 ERA, 26.1% strikeout rate and 7.9% walk rate. Miller has pitched 12 2/3 scoreless innings in his return to Phoenix, punching out a gaudy 31.9% of opponents against an 8.5% walk rate.

The 29-year-old Castillo isn’t likely to replicate the type of results that could’ve been expected from either Martinez or Puk, but he’s a reasonably experienced southpaw who’s had some prior success in the majors. Back in 2018-19, the southpaw looked to be breaking out as a viable bullpen arm for the division-rival Padres, pitching to a combined 3.23 ERA with a 35% strikeout rate and 8.4% walk rate in his first 39 big league innings.

Injuries have blown up Castillo’s career since. He suffered a torn ligament in his hand that cut his 2019 season short. A torn lat wiped out his 2020 season. He underwent Tommy John surgery in 2021 and missed most of the 2022 season as a result. It’s a staggering run of unfortunate maladies for the southpaw, but he’s shown some encouraging signs since joining the D-backs on a minor league deal last year.

In 24 innings between Arizona’s Rookie-ball and Triple-A affiliates last year, Castillo notched a 3.75 ERA. He whiffed 24.1% of his opponents and issued walks at an 8.1% clip with Triple-A Reno. This year, he’s started out by holding opponents to a run on four hits and no walks with seven strikeouts in 5 1/3 frames. Castillo has had an arduous grind to get back to the majors after pitching just two MLB frames from 2019-23. He’s now poised for his first real look in a bullpen since 2018, despite accumulating four years of MLB service time through his various stints on the 60-day injured list.

Because he only has four years of service, Castillo could be a multi-year option for Arizona if he can get back to his early career form. Enough time has already elapsed that he won’t be able to reach five years of service before the conclusion of the 2025 season. That means even if he’s back in the majors for good — and that’s far, far from certain — he can be controlled through the 2027 campaign via arbitration.

Diamondbacks Re-Sign Jose Castillo To Minor League Deal

By Anthony Franco | November 27, 2024 at 9:12pm CDT

The D-Backs are bringing back lefty reliever José Castillo on a minor league deal, reports Daniel Álvarez-Montes of El Extrabase (X link). Castillo, a client of OL Baseball Group, will get a non-roster invite to MLB camp.

Castillo sticks in the organization for a second season. He spent last year with the Snakes’ top affiliate in Reno. He missed the first half of the year to injury and was limited to 21 appearances. He tossed 20 2/3 innings of 4.35 ERA ball in a very tough park for pitchers. Castillo fanned a decent 24.4% of opponents against an 8.1% walk rate. His fastball averaged 94.3 MPH, a tick below the level he showed with the Padres in 2023.

That generally solid performance wasn’t enough to get a big league look with the Snakes a year ago. Still, Castillo sufficiently impressed the front office to get another non-roster invite. While he didn’t reach the majors last year, he pitched in parts of four seasons with San Diego. The Venezuelan-born southpaw has a 4.24 ERA in 40 1/3 big league innings.

A.J. Puk, Joe Mantiply and Kyle Nelson are the three lefty relievers on Arizona’s 40-man roster. Tommy Henry and Blake Walston could work in long relief or as rotation depth. Puk will pitch in high leverage spots, while the soft-tossing Mantiply has been a steady contributor in the middle innings. Nelson missed almost all of last season after undergoing surgery to treat thoracic outlet syndrome, so he could find himself on the roster bubble in Spring Training. Andrew Saalfrank will be an option midway through the season. He’ll remain on the restricted list into June after being issued a one-year suspension for betting on MLB games while he was in the low minors.

Diamondbacks Release Elvis Andrus

By Steve Adams | March 22, 2024 at 11:12am CDT

The Diamondbacks announced Friday that they’ve released shortstop Elvis Andrus, who’d been in camp on a minor league deal. Arizona also optioned first baseman/outfielder Pavin Smith and lefty Andrew Saalfrank to Triple-A Reno. Additionally, non-roster lefty Jose Castillo was reassigned to minor league camp.

Andrus, 35, signed a minor league pact with the Snakes earlier this month. He made it into six official Cactus League games and went 2-for-17 with a pair of singles, a walk and four strikeouts. The D-backs announced even before signing Andrus that Geraldo Perdomo would be the team’s everyday shortstop to begin the season, meaning Andrus was essentially competing for a bench role. The Diamondbacks will apparently stick with in-house options for that spot, including out-of-options third baseman Emmanuel Rivera and veteran utilityman Jace Peterson.

Andrus spent the 2023 season with the White Sox, who signed him in 2022 after his release by the A’s and re-signed him to a big league deal last winter. The two-time All-Star hit well for the South Siders down the stretch in 2022 — .271/.309/.464 (118 wRC+) — but he couldn’t replicate that output in 2023. Andrus opened last year as Chicago’s primary second baseman but hit just .251/.304/.358 (81 wRC+) in 406 plate appearances.

While he only has three career seasons of average or better offense (by measure of wRC+), Andrus has long been a premium defender and baserunner. He’s no longer the plus-plus defender he was at shortstop early in his career, but Andrus can handle any of shortstop, second base or third base — making him a viable utility option for a team in need of some versatility off the bench. His sprint speed dropped way down to the 30th percentile of MLB players last year, per Statcast, but his instincts on the bases still allowed him to swipe a dozen bags in 16 tries.

Diamondbacks Sign José Castillo To Minor League Deal

By Darragh McDonald | November 27, 2023 at 3:15pm CDT

The Diamondbacks have signed left-hander José Castillo to a minor league deal with an invitation to major league Spring Training, reports Tim Dierkes of MLB Trade Rumors. The lefty is repped by the OL Baseball Group.

Castillo, 28 in January, has spent most of his career with the Padres. He had an encouraging debut season for that club back in 2018, making 37 relief appearances as a 22-year-old with a 3.29 earned run average. He struck out 34.7% of batters he faced while giving out walks at just an 8% clip.

Unfortunately, he hasn’t been able to build off that, having been injured for most of the past five years. He was limited to just one big league appearance in 2019 due to a torn ligament in his hand. He missed the pandemic-shortened 2020 campaign due to a lat strain and then Tommy John surgery kept him out of action for all of 2021 and most of 2022.

He started 2023 on the IL due to a shoulder strain and eventually spent most of the season in the minors, making just one big league appearance. He was struggling badly in Triple-A as well, with an ERA of 9.82 in 22 appearances at that level when he was designated for assignment in July. He was then flipped to the Marlins for cash and made 14 more Triple-A appearances with a 5.59 ERA. He was passed through waivers in August and didn’t get his roster spot back by season’s end, leading to him hitting the open market.

For the Diamondbacks, there’s no harm in taking a flier on Castillo to see if he can finally get healthy and in a good groove. Despite their World Series run, pitching was a relative weakness for them in 2023, with a collective 4.48 ERA for the staff. Castillo is now out of options but he has just over four years of service time, meaning he could be retained beyond 2024 via arbitration if he is able to get back to that 2018 form.

29 Players Elect Free Agency

By Anthony Franco | October 6, 2023 at 4:33pm CDT

October brings postseason play for a handful of teams and their fanbases. Just over two-thirds of the league is now in offseason mode after being eliminated, however. As the season comes to a close, a number of veterans will hit minor league free agency.

These players are separate from six-year MLB free agents, who’ll reach the open market five days after the conclusion of the World Series. Eligible minor leaguers can begin electing free agency as soon as the regular season wraps up. These players were all outrighted off a team’s 40-man roster during the year and have the requisite service time and/or multiple career outrights necessary to reach free agency since they weren’t added back to teams’ rosters.

Electing free agency is the anticipated outcome for these players. There’ll surely be more to test the market in the coming weeks. We’ll offer periodic updates at MLBTR. The first group, courtesy of the transaction tracker at MiLB.com:

Marlins Outright José Castillo

By Darragh McDonald | August 10, 2023 at 5:45pm CDT

The Marlins have outrighted left-hander José Castillo to Triple-A Jacksonville, per Jordan McPherson of the Miami Herald. There had been no previous indication that the club had designated him for assignment, but they evidently passed him through waivers in recent days. The club’s 40-man roster count drops to 39.

Castillo, 27, has only been a member of the organization for a short time, having been acquired from the Padres in a cash deal just over two weeks ago. He had a solid major league debut with the Friars back in 2018, tossing 38 1/3 innings while allowing 3.29 earned runs per nine frames. He struck out 34.7% of the batters that came to the plate while walking 8% of them.

Unfortunately, injuries have prevented him from building off that strong first impression. A torn ligament in his hand limited him to just two thirds of an inning in 2019, then a lat strain wiped out his 2020. He then required Tommy John surgery in March of 2021, which kept him on the shelf until last summer, with the Padres mostly keeping him in the minors for the final months of the year. He finished 2022 with a strong 2.91 ERA in 43 Triple-A appearances.

But here in 2023, a left shoulder strain put him on the IL to start the year and he made just one major league appearance in early July, allowing four earned runs in a third of an inning. His work in Triple-A hasn’t been pretty this year either, with a 12.27 ERA in 22 frames at that level between the two organizations.

Those injuries and poor recent results likely helped him slip through waivers unclaimed. He’s also in his final option year, meaning he’ll be out of options for 2024. He has the right to reject this assignment since he has over three years of major league service time. However, he lacks the five years of service necessary to reject it and also retain his salary.

He and the Padres avoided arbitration in the winter by agreeing to a $730K salary for 2023, with about $240K left to be paid out. He would have to leave that money on the table for the right to pursue other opportunities, so perhaps he will stick with the Marlins to provide them with some depth but without using a spot on the 40-man roster. He’ll qualify for minor league free agency at season’s end if he still doesn’t have a roster spot at that time.

Marlins Acquire Jose Castillo From Padres

By Steve Adams | July 25, 2023 at 11:05am CDT

The Marlins have acquired left-handed reliever Jose Castillo from the Padres in exchange for cash, per a team announcement. Castillo, whom the Padres designated for assignment last week, has been optioned to Triple-A Jacksonville. Miami had an opening on its 40-man roster, so a corresponding transaction isn’t necessary.

The 27-year-old Castillo had a strong debut with the Padres back in 2018 but has been clobbered with injuries since that time. His 2019 season ended after just two-thirds of an inning due to a torn ligament in his hand. He missed the shortened 2020 season due to a lat strain and had the bulk of his 2021-22 campaigns wiped out following Tommy John surgery.

Castillo logged a sharp 3.23 ERA in his first 39 big league innings, fanning 35.1% of his opponents against an 8.4% walk rate. However, he’s pitched just two big league innings since the start of the 2019 campaign due to that litany of injuries.

Castillo did return to the mound in the minors last season, notching a tidy 2.59 ERA in 48 1/3 innings between Class-A and Triple-A. However, he’s been rocked for a 9.82 ERA in 18 1/3 Triple-A frames so far in 2023 and surrendered four runs in just one-third of an inning in his lone MLB appearance this year.

This is Castillo’s final minor league option season, so he’ll need to establish himself as a viable big league bullpen option before season’s end or else be at risk of being subtracted from the 40-man roster this offseason. He’s already over three years of Major League service time — most of it spent on the injured list — so he’ll be arbitration-eligible this winter and would be a clear non-tender candidate if he can’t take a step forward in his new organization. And, because he has more than three years of service, he’d become a free agent at season’s end if he’s outrighted before that time.

Padres Designate Jose Castillo For Assignment

By Steve Adams | July 20, 2023 at 10:41am CDT

The Padres have designated left-hander Jose Castillo for assignment and optioned righty Matt Waldron to Triple-A El Paso, per a team announcement. That pair of moves clears roster space for righty Robert Suarez, who has been formally reinstated from the 60-day injured list.

Castillo, 27, posted a strong 3.23 ERA through his first 39 big league innings back in 2018-19 but has since seen that promising debut derailed by injury. His 2019 season was cut short by a torn ligament in his hand, and he missed the 2020 season due to a lat strain. Castillo’s 2021 campaign and much of his 2022 season were then wiped out by Tommy John surgery. He’s pitched just two total MLB frames dating back to 2019.

While Castillo posted solid numbers in the upper minors last year as he returned from that deluge of injuries, he’s struggled immensely in 2023. His lone MLB appearance saw him yield four runs in one-third of an inning, and he’s been tagged for a 9.82 ERA in 18 1/3 frames of Triple-A ball.

Castillo is in his final option season and will be arbitration-eligible this winter. The Padres will have a week to trade him, attempt to pass him through outright waivers or release him. If another team picks him up, he can be optioned for the remainder of the season but would need to be carried on the active MLB roster beginning next season. That said, if he can get back on track with a new club, he’d have an additional two seasons of club control remaining.

Suarez, 32, fanned 32% of his opponents and notched a 2.27 ERA as a 31-year-old rookie in San Diego last season after a years-long run of excellence in Japan’s Nippon Professional Baseball. The Friars re-signed to a five-year, $46MM deal with an opt-out clause early last offseason, but he’s yet to pitch this season due to an elbow issue. He’ll give San Diego a high-quality arm to slot into the late innings as the Padres try to salvage an immensely disappointing start to their 2023 season.
